Topic awaiting preservation: Need an Opera hook

This script is what I'm using to determine browser type and, as is obvious, it doesn't include a hook for Opera.
<BLOCKQUOTE><FONT face="Verdana, Arial">code:</font><HR><pre><script language="JavaScript">
var nn4= (document.layers);
var nn6= (document.getElementById && !document.all);
var ie4= (document.all && !document.getElementById);
var ie5= (document.all && document.getElementById);

function loadPage(id,nestref,url) {
// change the 550 value to make the layer wider or smaller
content_width = 350;
if (nn4) {
var lyr = (nestref)? eval('document.'+nestref+'.document.'+id) : document.layers[id]
lyr.load(url,content_width)
}
else if(ie4) parent.contentFRM.location = url;
else if(ie5

There's actually some extra code here, you shouldn't need to code for the 6+ browsers sperately since both conform to the DOM and nestref looks like it is never getting set.

I thought the Opera (6 especially) browsers conform to the DOM and should get handled as nn6 but I don't use them much so I can't say for sure.

Sorry I don't currently have these installed so I can't give a better answer.

As I understand this code, nesref allows the linking call
("javascript:loadPage('contentLayer',null,'lim.htm')")
to refer to a nested div location, namely,

<div id="content">
<div id="contentLayer">
<iframe src="index2.html" name="contentFRM" id="contentFRM" width="100%" height="330" frameborder="0" hspace="5" vspace="5"></iframe>
</div>
</div>

Notice how contentLayer is called by loadPage? Anyway, that's how I understand it. When the link is activated, lim.htm displays in the iFrame, formatted by content and contentLayer, and nestref tells the script where contentLayer is...? Can I just create another variable and conditional statement to handle it?
Something like
var O6= (document.getElementById && !document.all);

and use something like

if (O6) {var lyr = (nestref)? eval('document.'+nestref+'.document.'+id) : document.layers[id]lyr.load(url,content_width)}

to laod the page into the iFrame? Probably way off here, but looking for guidance.

No takers?

Opera wont work with that script becuase the iframe element is not exposed to scripting. Go figure.......

document.all will work in Opera only when it is running in MSIE compatibility mode (otherwise document.getElementById is only one that's available)...

Ok, thanks for clearing that up for me!
